Steps to convert the latitude and longitude WGS84 geographic coordinate system to CGCS2000 coordinate system

From GIS frontier WeChat public account

1. Export the layer from Ovi into a shp file.

2. Open arcgis-arcmap

3. Geoprocessing-arctoolbox-data management tool-projection and transformation-elements-projection


4. Convert WGS84 coordinates to geographic coordinate system-world- ITRF2000




5. Open ArcCatalog, find the shp file that has become ITRF2000 coordinate system in the previous step, right-click-properties, redefine the layer coordinates to GCGS2000 geographic coordinate system



6. Reopen arcmap, and reopen the redefined coordinate system shp file, according to geoprocessing-arctoolbox-data management tool-projection and transformation-elements-projection




7. Regarding the calculation method of band number




If the band number is not used, the central longitude of the area is used, which

is 3 degrees with the central longitude line.

If the front Plus belt number, adopt 6-degree belt or third-degree belt number, both are three-degree belt number

8. Calculation After
converting the GCGS2000 geographic coordinate system to the GCGS2000 projection coordinate system in the previous step, open the shp file converted into the projection coordinate system in the previous step, click the layer, right-click properties, and change the decimal unit to meters in the general.
Then right-click the shp layer, open the attribute table, add fields, add x, y coordinate fields

*One thing to pay attention to here, we are choosing the belt number before, there is a belt number, and there is no belt number, if there is a belt number, then the calculated y (corresponding to the longitude) is 8 digits, if there is no belt number, The corresponding y (corresponding to longitude) is 6 digits; x (corresponding to latitude) is 7 digits, unchanged.
